In this thesis, the effects on regular waves when propagating from deep to shallow water have been investigated, assuming linear wave theory. The effects of shoaling, refraction, reflection and diffraction have been studied. ...

The dimensions of offshore wind turbine (OWT) support structures are governed by fatigue considerations. For 6‐ to 10‐MW OWTs, wave loads are often dominating in terms of fatigue utilization. The present work proposes a ...

The main objective of this work is to study wave loads on floaters of fish farms. Several incidents of major fish escapes due to structural collapse of fish farms in harsh weather have motivated this study, as a step towards ...

Under way replenishment between two ships is a critical operation, and accidents have been reported. Hydrodynamic interaction between the hulls may influence the forces and the motions of the vessels, and both manoeuvring ...

Denne masteroppgaven presenterer alternative metoder for bølgelastkompensasjon i dynamiske posisjonering (DP) av marine fartøy, der stabile og robuste konvensjonelle kontrollere med tilbakekopling vanligvis brukes. Slike ...

The paper addresses how the wave power for sea states can be assessed based on available wind statistics for an ocean area. Results using a simple analytical tool are exemplified for a Pierson–Moskowitz wave spectrum ...

Recent environmental considerations, as salmon lice, escape of farmed fish and release of nutrients, have prompted the aquaculture industry to consider the use of closed fish production systems (CFPS). The use of such ...

In the resent years the fear of violent storms occuring more often, and with increasing violence, has drawn new attention to research on wave runup and wave rundown. Severe storm conditions could cause great damage on ...

In critical sea states, semi-submersibles may experience large negative air gaps in which incoming waves cause large slamming loads that may lead to severe structural deformations. Wave loads due to slamming are difficult ...
